A simple and efficient Mn-catalyzed acylation of amines is achieved using both acyl and alkoxy functions of unactivated esters with the liberation of molecular hydrogen as a sole byproduct. The present protocol provides an atom-economical and sustainable route for the synthesis of amides from esters by employing an earth-abundant manganese salt and inexpensive phosphine-free tridentate ligand.
使用未活化的酯的酰基和烷氧基官能团,同时释放分子氢作为唯一的副产物,可实现胺的简单有效的Mn催化酰化反应。本方案提供了一种原子经济且可持续的途径,可通过使用富含地球的
